10.4: Boot another OS while OS X is hibernating
Authored by: neuralstatic on Mar 06, '07 08:51:13AM
either i'm crazy, or this can't be what he meant....
"Actually, this isn't strictly necessary: you can also put your Mac to sleep and then remove the battery (on a laptop) or unplug the AC cord (on a desktop) to make it go to Deep Sleep."
taking power away from a regularlyl sleeping mac can't make it write to the hard drive an impromptu hibernation session....

The hibernation information is written on the front end as the computer goes to sleep. See this article (written by none other than robg) on deep sleep.

10.4: Boot another OS while OS X is hibernating

ALL modern macs basically hibernate when put to sleep. If power is not lost, it wakes up instantly. If power was lost, it will take a minute, but it will restore itself.

So yes, that is what he meant. If you remove power, the computer still has the hibernation image.
